grommunio-admin dbconf — Database-stored configuration management.
Synopsis
Section titled “Synopsis”grommunio-admin dbconf (commit | delete) SERVICE [FILE [KEY]]
grommunio-admin dbconf get SERVICE FILE [KEY]
grommunio-admin dbconf list [SERVICE [FILE [KEY]]]
grommunio-admin dbconf set [-b] [-i] [--] SERVICE FILE KEY VALUE
Description
Section titled “Description”grommunio dbconf provides the ability to store and manage configurations at a single location while making it available across distributed systems. The configurations are stored in the central MySQL database and can be accessed via grommunio-dbconf(1) and grommunio-admin-dbconf(1).
While both tools essentially provide the same functionality, grommunio-dbconf(1) provides far better performance and is intended to be used for quickly accessing the configuration.
Configurations consist of key/value pairs organized in files, grouped by service. Each service can have an arbitrary number of configuration files, which in turn can contain an arbitrary number of unique keys.
Commands
Section titled “Commands”commit
Trigger commit hook for service, file or key
delete
Delete service, file or key
get
Get file or single key
list
List available services, files or keys
set

Options
Section titled “Options”SERVICE
Name of the service to configure
FILE
Name of the configuration file
KEY
Name of the configuration key
VALUE
Value to store in the key
--
Indicate that all options have been specified and only names follow
-b, --batch
Do not auto-commit
-i, --init
Only set if configuration key does not exist yet
grommunio-admin
Section titled “grommunio-admin”The grommunio-admin API and CLI are also dbconf consumers. This allows system adiministrators to change certain configurations without filesystem access and the need to restart the API.
The following files and keys are meaningful when placed under the grommunio-admin service:
multi-server
Section titled “multi-server”policy
Server selection policy for newly created users and domains in multi-server environments. Possible values are balanced, first, last, random and round-robin. Default is round-robin.
Commit Hooks
Section titled “Commit Hooks”When modifying values, potential consumers can be notified of this change via commit hooks, for example by restarting the service using the configuration. For security reasons only a few white-listed commands are available (see section AVAILABLE COMMIT COMMANDS).
Commit hooks can be defined on key, file or service level. set operations always trigger commits at key level, while the commit command can directly trigger key or service level hooks depending on whether a file or key is specified.
If no hook is defined for a specific trigger level, it automatically falls through to the next lower level, in the order key > file > service.
Commit hooks for a service can be defined by setting commit_key, commit_file and commit_service keys under grommunio-dbconf/<service> to a valid command (see below).
Available Commit Commands
Section titled “Available Commit Commands”The following commands are available:
postconf -e $ENTRY
postconf -e $FILE_S && systemctl reload postfix
Service
Section titled “Service”systemctl reload $SERVICE
systemctl restart $SERVICE
Macros
Section titled “Macros”As the whitelisted commands might be hard to memorize and may be changed in the future, macros are provided that expand to whitelisted commands.
The following macros are defined:
#POSTCONF -> postconf -e $ENTRY
#POSTCONF -> sudo postconf -e $FILE_S && systemctl reload postfix
Service
Section titled “Service”#RELOAD -> systemctl reload $SERVICE
#RESTART -> systemctl restart $SERVICE
Command Variable Expansion
Section titled “Command Variable Expansion”Commands can contain $-prefixed variables that are expanded before execution. The literal $$ can be used to generate a single $.
The following variables are valid:
ENTRY
Expands to $KEY=$VALUE (key level only)
FILE
Complete content of the modified file as newline separated key=value entries (file level only)
FILE_S
Complete content of the modified file as space separated key=value entries (file level only)
FILENAME
Name of the modified file (key and file level)
KEY
The modified key (key level only)
SERVICE
Name of the modified service
VALUE
New value of the modified key (key level only)
